The first multistage image converter with an X-ray photocathode (UMI-93 SR) was designed in
VNIIOFI in 1974 [1]. The experiments carried out in IOFAN pointed out that X-ray electron-optical
cameras using the tube provided temporal resolution up to 12 picoseconds [2]. The later work has
developed into the creation of the separate streak and intensifying tubes. Thus, PV-003R tube has
been built on base of UMI-93SR design, fibre optically connected to PMU-2V image intensifier
carrying microchannel plate.
